[SOLVED] 4 sticks of RAM on H170 Mobo

[leinad4]

Hi

I currently have 2x 8gb ram on my Asus H170 Pro Gaming motherboard and I am looking to upgrade to 32gb of RAM, but I don't want to spend £200+ on a set of 2x 16gb.
I am considering buying another identical set of the 2x 8gb I have but unsure whether the motherboard supports 4 sticks of RAM or if 2x 16gb would be a better option.

That motherboard supports 4 but 2 would be faster. What model are you looking at for the ram.

Your board supports 4x 8GB sticks but it'll be a crapshoot as to whether 2 kits of 2x 8GB sticks each will work together. To guarantee compatibility you would need to purchase a 4x 8GB kit.

That should be the QVL list for your board. You can put up to 16GB DIMMs in each slot. So yes 4 8GB should be fine.

However I don't really recommend doing it they way you are, buying a kit is best. Even if you get the same model there may be slight differences that can cause instability. a 32GB kit is pretty much factory matched and guaranteed to work.

Adding ram is a crap shoot, it may work perfectly, it might need slight adjustments to VCCIO (memory controller voltage) or a bump to vram, or might not work at all.

Ram is made up of IC chips made from silicon. Each stick in a kit is factory tested for compatability. When you get sticks in a different kit, even the very next kit on the peg, same brand, size, speed, model, they are not tested. They can even be different IC's from different companies. But chances are good that they are going to be from different batches of silicon, which has different impurities, which changes the secondary or even tertiary timings (there's over 40 of those, not just the primary 5).

So yes, you can add 2x more 8Gb sticks, but they may conflict with your existing sticks. There's absolutely no way to tell until you try them. Or there may be no conflict at all and everything runs great.

A brand new kit the size you want is the only way to guarantee compatability.

Thanks for the advice, I will just get a kit instead. I actually searched for the exact RAM I have again but can't find it for sale with the same memory speed as the ones I have. Thanks!
